Abstract: Techniques are provided for identifying and recording program segments and sub-segments for later playback and use. In general, in one aspect, the invention features a method of recording a sub-segment of a broadcast program. The method includes receiving a user input of one or more user specified parameters, identifying a program sub-segment starting point within a program using data in a broadcast stream, and identifying a program sub-segment ending point within a program. The method also includes storing a program sub-segment and presenting the program sub-segment to a user.

Abstract: Systems and techniques for sharing the capabilities of consumer electronic devices. In one aspect, a method includes receiving a task involving audio/video content from a user, identifying which device in an interconnected system of devices is operable to initiate the performance of the task, and assigning responsibility for the performance of the task to the identified device. The interconnected system includes two or more devices at remote locations.

Abstract: Techniques for resolving scheduling conflicts for recording events are described. A user selects events that the user wishes to record. A PVR determines the times and sources at which each of recording can occur. The PVR determines a schedule for recording all of the user's requested events or as many events that can be recorded according to the resources available to the PVR. The PVR can be triggered to determine the schedule each time a new recording event is either added to deleted. The PVR can also determine the schedule each time the PVR receives updated or new scheduling information. If more than one schedule is determined, the PVR can present the schedules to the user for selection. The user's selection can be subsequently used to inform the PVR of the user's preferences the next time schedules are determined.

Abstract: Systems and techniques for controlling access to content. In one implementation, a method includes receiving a criterion identifying acceptable television content for a certain accessor, receiving information describing features of currently available television content, comparing the features with the criterion, and allowing the accessor to view the television content only if the features of the television content meet the identifying criterion.
